Hello My name is Simon and this is my first post. I came here after finding a link on the Ask Jack column in the Guardian. My problem is that a few months ago the speed of my internet browsing slowed down considerably. It was particularly apparent when downloading or watching youtube for example. After about a month it suddenly speeded up again without me having done anything in particular to resolve the problem. This has now happened a further 2 or 3 times. It has been slow again over the past week so I have now followed Howard's routine to cleanse my pc and I attach my 3 log files as suggested. I would like someone to look at these and advise. I also attach a 4th log file showing the results of a bitdefender online scan that I performed earlier. The pc seems to have speeded up again after this process so maybe the problem has been solved but I would still like someone to look at the log files and offer further advice or help if required. Many thanks. Simon.
